Sorry if this has been answered but I wasn't able to find a similar scenario and there are so many variables to consider with specific migrations. I would appreciate any and all input in this.
We currently have a Oracle SDE GeoDatabase system running in a 10.0 environment with an ArcFM module. Clients consist of a few ArcGIS desktops and a couple of smaller custom GeoView/Explorer clients and such. We are getting ready to ramp up to having a GISServer and new development so we want to bring everything to 10.3. We do have time, so it does not have to be a switch and done in one night. We want to slowly bring the DB's/Schema's over to the 10.3 platform as we redevelop and upgrade the existing apps. We have a lot of cleaning up to do so we want to use this opportunity to move one data-set over at a time until we get to the point we need to do a "switch" with the remaining users and apps.
The basic idea we are thinking is to setup and new Oracle DBMS on a new server create a new SDE instance of 10.3 and then using a 10.3 client like ArcCatalog simply copy and paste the old to the new. Will this work and maintain all of the data AND update the GeoDB version? or is it going to be more complicated than this?
Thanks for any and all input!
